If no higher or lower speed is posted, what is the speed limit within city limits for all vehicles?

The correct answer reflects the standard speed limit within city limits for all vehicles when no other speed is posted. In many jurisdictions, including those applicable to U.S. forces driving in Europe, the default speed limit in urban areas is commonly set at 50 kilometers per hour, which is approximately 31 miles per hour. This limit is established to promote safety in populated areas where higher speeds could increase the risk of accidents involving pedestrians, cyclists, and other vehicles.

Understanding this speed limit is crucial for drivers to comply with local traffic regulations and to ensure safe driving practices in urban environments. The provided options, which range from lower to higher speeds, demonstrate the variability of speed limits, but the absence of additional markings designates 50 kph as the standard limit in most cities.
